Abstract: In this paper, we investigate the energy efficiency (EE) optimization in the user-centric cell-free massive MIMO (CF mMIMO) systems for ultra-reliable low-latency (URLLC), where access ...
Abstract: Solving Mixed Integer Linear Programming (MILP) problems is of considerable practical importance. The Branch and bound (B&B) method is widely used to solve MILP problems. In this paper, we ...
